HOMILETICS. Ver. 19.-Moral avalanches- not easily arrested when once set in motion. The magicians had begun by exciting Pharaoh to obstinate unbelief and resistance to the Divine Will. They had, by artifice or otherwise, persuaded him that there was nothing ~o very marvellous in the wonders wrought by Moses and Aaron, nothing th11.t indicated a Divine author of the wonders. They had thus encouraged and stimulated him to embark upon a fatal course. Now, they would fain have stopped him, but they could not. His pride and self-conceit-his honour, as no doubt he thought it, were concerned in the struggle upon which he had entered-to give way would be to acknowledge himself worsted in a contest with two contemptible Hebrews. In vain did the magicians change their tone, and make the acknowledgment-" This is the finger of God "-their altered spirit had no effect upon him. No-whoever changed or blenched-he would persevere -his heart had become hardened-if now and then he quailed. and seemed on the verge of yielding, yet after a time he drew back-always provoking God more and more by his continual perverseness, until at last all Egypt was involved in destruction (eh. xii. 29, 30; xiv. 27-30). The magicians, who had had a large share in causing his entrance upon an evil course, found themselves unable to arrest his steps, and must be regarded as in part responsible for the final catastrophe. So nations are often urged by evil counsellors into wars or rebellions, which they soon bitterly regret; but it is too late to stop the evil. Men in business are reco=ended to adopt questionable means of pushing or retrieving their fortunes, and embark on courses from which their advisers would fain withdraw them; but it is impossible. Advisers should recognise the great- ness of their responsibility from the first, and set themselves against the very beginning of evil, else they will find the course of affairs soon get beyond their control-they will be utterly powerless to stop the avalanche which they have set in motion.
